For geological surveys of different sections of the Quaternary deposits of Jam aquifer, using depth data of wells and geoelectric boreholes, 51 wells and boreholes were used to extract depth of sections. In the GMS software by selecting ID, Quaternary deposits were identified and coded in wells and Sondage. Based on geo-electric sections of the Jam Plain, Due to the prevailing electrical resistance (Ohm Meter) and analysis of sample Sondages, three classes of quaternary deposits including dry alluvial deposits(Q2), Juicy alluvial deposits(Q1) and the marl Bedrock were separated. After entering quaternary deposits data into ArcGIS software, by logarithm, normalizing the data was done. The results showed the Jam  aquifer bed rock in the northwest of pure red clay, in the northern part of the green marl and the middle part of the bed rock is pure marl. Surface layer contains alluvial deposits (Q2) and below it, the layer contains juicy alluvial deposits (Q1). Marl bed rock is seen all the way through the sections. The maximum height is 730 m in the northeastern plain and at least 630 meters in the northwest. The study showed that the major thickness of quaternary deposits Q2 is located in the northeastern region of the study area and in the middle and northwest of the plain, the thickness of Q2 has been reduced. Quaternary deposits thickness Q1 in the northwest to northeast, especially in the middle of the plain increase. The characteristics of quaternary deposits of the study area, lack of surface watery layers, high permeability and reduced clay impurities. The results of the study showed in dry alluvial deposits and Juicy alluvial deposits, there is a direct correlation between hydrodynamic coefficients and thickness variations of quaternary deposits. With reduction in the thickness of alluvial deposits, the hydrodynamic coefficients are also reduced.
